VIDEO DETECTION METHOD, VIDEO DETECTION DEVICE, AND VIDEO DETECTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To accurately and efficiently detect advertisement video.

SOLUTION: A video detection device 1 comprises: a structure analysis part 101 for analyzing a section structure of an input video and dividing it into partial sections; a candidate section detection part 102 for detecting one or more candidate sections including an advertisement video on the basis of characteristics of the partial sections, and finding its start time and its completion time; a shot characteristic extraction part 103 for analyzing at least one of an image and a sound in the partial section existing inside the start time and the completion time of the candidate section, and extracting a characteristic amount; a coding part 104 for expressing the partial sections by codes on the basis of the characteristic amount; a recursive code sequence detection part 105 for detecting a group of the partial sections to be code sequences recursively appearing from the code sequences constituted by one or more partial sections expressed by the codes; and a filter part 106 for outputting only the partial sections satisfying a predetermined condition as an advertisement video section among the group of the detected partial sections.
